Version History of Municipalities 2015 (1:4 500 000) - Table

The 'table__history' is a rich repository of historical data, serving as a version history for its base table rows. Originating from the 'Tilastokeskus' (Statistics Finland) website, this table belongs to the 'tilastointialueet_kunta4500k_2015' dataset collection. The table provides a detailed account of Finnish municipalities as of the year 2015 at a scale of 1:4,500,000.

The data is organized in a range of columns that contain diverse pieces of information. Of particular note are two special columns: '_start_date' and '_end_date'. The former specifies the date when a particular row was extracted from the source, while the latter indicates when a new version of that row was sourced. If an '_end_date' is null, it signifies that the associated row is the most recent version. Additionally, each row in this version history table can be uniquely identified by a combination of '_start_date' and '_row_number', the latter of which indicates the row's position in the raw data extracted from the source.

A considerable part of the data set is dedicated to geospatial information, which can be invaluable for geospatial data analytics. This includes geographic coordinates presented using the WGS 84 coordinate reference system, with the longitude specified first, followed by latitude. A variety of columns beginning with 'geom_' provide this data in different formats, including 'geom_geojson', 'geom_geotext', and 'geom_centroid'.

The table also contains other information about the municipalities, such as their names in different languages and certain geometric properties. This data can be used in a wide range of analytical scenarios. For instance, historical trends in municipal data could be analyzed using the version history information. Additionally, the geospatial data could be used to visualize geographical distributions or changes over time. The table's rich set of data could also support more complex geographic information system (GIS) applications.
